    Power cycle your equipment and try again...
    (turn off router, modem and system...wait >30 seconds...power up in order, allowing time to 'go green' ...modem, router, system)

    I did that several times, with the same result.

    Remove and reconnect all connections to modem and router.
    Change port on router.
    If other computers on network can connect to internet and this is the exception, skip next two steps.
    If no fix, replace router with known good.
    If no fix, replace modem with known good.
    Check Device Manager for status of network controller.

    I found the root cause, and it's very silly!
    What happened was that the LAN/Ethernet cable was connected to the modem, not the router.

    When called the ISP customer service:
    • 1st Representative (8th June): Asked to connect the phone line to the TEL1 port, disregarding the DSL port
    • 2nd Representative (9th June): Asked to connect the LAN/Ethernet cable from modem to computer*
    • 3rd Representative (today, 10th June): Said connecting to modem is incorrect, should be connected to the router -> connect to router -> issue resolved
    *Point after when I started this thread

    Thanks for the help Cycloid, this thread can be closed.
